Answer:

Step-by-step explanation:
Let
h -----> the height of the building
x -----> the horizontal distance between the building and the tower
we know that

solve for x
-----> equation A

solve for x
------> equation B
equate equation A and equation B and solve for h

Answer:
C. y-7=2(x-6)
Step-by-step explanation:
y2-y1/x2-x1
7-(-9)/6-(-2)
7+9/6+2
16/8
m=2
y-y1=m(x-x1)
y-7=2(x-6)
124° Is your answer.
The triangle Is an isosceles triangle which means the two bases will be the same angle. 180° is this sum of all angles in a triangle. If 62 is the right base angle then 62 must be the left base angle since is an isosceles triangle. Add 62 and 62 together then subtract from 180. That would give you 54° as the third angle angle at top. Since you are looking for a Z, we now know that z and 54° are symmetry and equal 180 when added together. We then subtract 54 from 180 to get the angle of z.
Answer:
x=7
Step-by-step explanation:
Since these angles are complementary, they will add up to 90 degrees, so you can set up the equation like so:
8x+5+3x+8=90
First, combine like terms:
(8x+3x)+(5+8)=90
11x+13=90
Then, subtract 13 from both sides:
11x+13(-13)=90(-13)
11x=77
Then divide both sides by 11:
11x(/11)=77(/11)
x=7
7 is your answer

Palindromes are numbers whose reverse is the same as the original number
There are twenty-five 5-digit palindromic numbers, that have digits that add up to 14
<h3>How to determine the count of 4-digit palindromes</h3>
The digit of the palindromic number is 5.
This means that:
- The first digit of the palindrome can be any of 1 to 7 (because 7 is half of 14)
- The second digit can be any of 0 - 6 (i.e. 7 digits)
- The third digit can be any of 9 digits
- The fourth digit must be the second digit (i.e. 1 digit)
- The last digit must be the first digit (i.e. 1 digit)
So, the total number of digits is:


Hence, there are twenty-five 5-digit palindromic numbers, that have digits that add up to 14
